---------------------------------------------------------------
Ah... I've always used Ninja on Windows for Arrow. I guess msbuild is slower,
at least that's what AppVeyor seems to indicate.
I think at some point I recommended Ninja in our Windows build docs, but I
can't seem to find the change.

> Link times are a significant drag in MSVC builds. They don't affect Linux
> nearly as much when building with Ninja. I suggest we combine some of the
